    Research Summary

    Dr. Nimmagadda’s research focuses on the development of imaging agents for early detection of metastatic disease. His current work examines the role of chemokine receptors in cancer progression and metastasis. Ongoing studies include the development and evaluation of positron emission tomography (PET), single photon emission computed tomography (SPECT) based radiopharmaceuticals and optical imaging agents for chemokine receptors four and seven (CXCR4 and CXCR7).
